Lesser Goldfinch Recorded In Nebraska, Phil Swanson

Nebraska Bird Review

I photographed this Lesser Goldfinch (Carduelis psaltria) at Gilbert-Baker Wildlife Area (north of Harrison, Nebraska) about 9:00 a.m. on 20 May 1984. The bird was in the campground area with American Goldfinches. I watched the Lesser Goldfinch with binoculars for a few minutes before I took the photograph and easily noted the field marks. The bird was the black-backed variety (C. p. psaltria).

The Eighty-Third Annual Meeting

Functional Cranial Analysis Of Large Animalivorous Bats (Microchiroptera), Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Large animalivorous bats include carnivorous, piscivorous and insectivorous microchiropterans. Skull proportions and tooth morphology are examined and interpreted functionally. Four wide-faced bats from four families are convergent in having wide skulls, large masseter muscle volumes and stout jaws, indicating a powerful bite. Three of the four also have long canine teeth relative to their maxillary toothrows. Carnivorous bats have more elongate skulls, larger brain volumes and larger pinnae. The wide-faced bats are all oral emitters and have heads positively tilted relative to the basicranial axis. The carnivorous species are nasal-emitting bats and have negatively tilted heads. The orientation of the …

The Hellbender, Cryptobranchus Alleganiensis, In Indiana, William H. Kern Jr.

All-Inclusive List of Electronic Theses and Dissertations

Very 1 ittle was previously known ubout the Hellbender, Crrp:t:£branchus alleganiensis alleganiensis, in Indiana. The purpose of this study was to determine its current range and status in Indiana and collect life history information. The hell benders were captured by hand from under rocks and 1d th hoopnets baited with cut fish. They were tagged, measured, wei~hed, examined for large external parasites, wounds, and reproductive cond:i - tion. Stoma ch contents were taken with a non-lethal, stomach-flushfog technique. The animals were then released at the site of capture. Al though they were originally found in the Ohio River, \\'hi tewater …

Distribution Of The Shoshone Scuplin (Cottus Greenei: Cottidae) In The Hagerman Valley Of South Central Idaho, Richard L. Wallace, J. S. Griffith Jr., D. M. Daley, Patrick J. Connolly, G. B. Beckham

Great Basin Naturalist

Cottus greenei, a potentially threatened species endemic to Idaho, was collected from 49 localities in 25 springs/streams in south central Idaho. Most localities were along the north bank of the Snake River in waters of the Thousand Springs formation, Gooding County. One population was found in a spring in the main Snake River. Another sculpin, Cottus bairdi, was collected with C. greenei at 23 locations in 16 springs/streams. Confusion concerning the type locality of Cottus greenei is discussed.>

Characterization Of The Dna And Chromosonal Analysis Of Embryonic Dermacentor Variabilis (Say) Cells In Culture, Stanley Nicholas Mason

Biological Sciences Theses & Dissertations

Cultured embryonic Dermacentor variabilis cells were examined by spectrophotometric techniques to determine total cellular DNA concentration and guanine-cytosine content of the DNA and by differential staining procedures to define the karyotype further. The cells were found to have a mean DNA content of 16.98 pg and a DNA guanine-cytosine content of 49%. Chromosome banding attempts resulted in the specific characterization of four chromosomes and differential grouping of the seven remaining chromosomes. A previously unreported submetacentric chromosome was identified.

Record Count For Whooping Cranes On The Platte River

Nebraska Bird Review

Since 1942, there have been eight confirmed Whooping Crane (Grus americana) sightings on the Platte River (Whooping Crane Recovery Team. 1983. List of confirmed whooping crane migration sightings of the Wood Buffalo - Arkansas population. U.S. Fish and Wild\. Serv., Washington, D.C. 18 pp.). The largest number of birds on the Platte was five although seven were seen flying along the Platte near Kearney in April 1980. On 27 October 1983, five adult Whooping Cranes were reported feeding in an idle cornfield 3.5 mi. NE of Denman in Hall County and later, these 5 individuals were observed landing …

The Effects Of Mowing On The Rodent Community Of A Native Tall Grass Prairie In Eastern Nebraska, Cliff A. Lemen, Mary K. Clausen

University of Nebraska State Museum: Mammalogy Papers

Our results indicate that mowing, like burning, greatly reduces the use of an area by Microtus and increases the density of Peromyscus maniculatus until the grass can grow back. Depending on the rate of growth of the grass this process can take more than a year. If the prairie is mowed every year to maximize the production of hay, populations of Microtus cannot be maintained at high densities.

The study site, Nine Mile Prairie, is one of the few natural tallgrass prairies remaining in eastern Nebraska. It covers about 240 acres and is located 5 km north and 9 km …

Warm Water Aquaculture Using Waste Heat And Water From Zero Discharge Power Plants In The Great Basin, Richard A. Heckmann, Robert N. Winget, Rex C. Infanger, Roger W. Mickelsen, John M. Hendersen

Great Basin Naturalist

Two series of experiments were completed to determine (a) toxicity of waste water from power plants on warm water fish and (b) multiple use of waste heat and water for aquatic animal and plant production. All three types of waste water from a typical coal-fired power plant are acceptable for growing catfish and tilapia following aeration. This growth was compared with fish raised in spring water. Closed, recirculating polyculture systems using evaporation pond water operated efficiently for plant (duckweed) and animal (fish and freshwater prawns) production. Duckweed is an excellent supplement for fish feed. Tilapia and freshwater prawns grew rapidly …

Invertebrates Consumed By Dabbling Ducks (Anatinae) On The Breeding Grounds, George A. Swanson

Journal of the Minnesota Academy of Science

Foods consumed by dabbling ducks on the breeding grounds of south-central North Dakota were investigated during the spring and summer of 1967-80. Invertebrates dominated the diet of laying females. Animal foods comprised 99%, 72%, and 77% of the diet of laying blue-winged teal and northern shovelers, gadwalls, and mallards, and northern pintails, respectively. Factors that influence food selection include morphological adaptations for feeding, current physiological demands, the nutritional value of food items, and food availability. Preservation of waterfowl production habitat requires that the value of the wetland complex be recognized. Temporary, seasonal, and semi permanent wetlands provide abundant and highly …

Potential Effects Of Insecticides On The Survival Of Dabbling Duck Broods, Patrick W. Brown, Malcolm L. Hunter Jr.

Journal of the Minnesota Academy of Science

The effect of insecticides on the survival of dabbling duck broods was investigated by reviewing studies of natural brood survival and depression of growth rates for ducklings raised on wetlands treated with insecticides. Ducklings raised on an insecticide-treated wetland took 5 days longer to reach the normal 14-day body weight. Normal brood mortality for three species of dabbling ducks was highest in the first two weeks of life and ranged from 25% to 51%. High mortality of young ducklings is probably related to their small size. Thus, mortality rates could be in creased to 35% to 70% because of the …

Microgeographic Variation In The Mexican Vole, Microtus Mexicanus, Meredith J. Hamilton, Gary A. Heidt

Journal of the Arkansas Academy of Science

Altitudinal variation was assessed in 115 (62 male; 53 female) Mexican voles (Microtus mexicanus) from six localities in Jalisco, Mexico. Univariate and multivariate statistical techniques were employed in the data analyses. A total of 49 skeletal measurements were investigated, and of these, 17 showed significant interlocality variation. Rostral breadth, depth of braincase, rostral height, width of third molar and nasal length were found to be the most variable characters. Component I (a size factor) accounted for 36% of the total phenetic variation; components II and III accounted for 30% and 19%, respectively. Larger individuals were found to occur at lower …

Limitations On Spatial Memory In Mice, Robert H.I. Dale, Martin Bedard

Scholarship and Professional Work - LAS

Rats have an impressive ability to remember locations they have visited. Two experiments used an eight-arm radial maze to determine whether mice showed two important characteristics of this spatial memory: its durability, and its dependence on stimuli outside the maze (extreme stimuli). In Experiment 1, food-deprived mice were allowed to eat from four of the eight arms of the maze then, after delays of 5 sec, 1 min, or 5 min, they were permitted to choose the remaining arms. Choice accuracy declined significantly with the longer delays, but always remained above chance. In Experiment 2, the maze was rotated 180° …

River Otter In Arkansas Iii. Characteristics Of Otter Latrines And Their Distribution Along Beaver-Inhabited Watercourses In Southwest Arkansas, Mark R. Karnes, C. Renn Tumlison

Journal of the Arkansas Academy of Science

Forty-one river otter (Lutra canadensis) fecal deposit (latrine) sites were located during April 1983 through March 1984 along beaver (Castor canadensis) inhabited watercourses in Clark, Nevada, and Ouachita counties, Arkansas. Latrine sizes ranged from 64 cm² to 5.01 m² (x-bar=0.30 m²; S.D. =0.88), and contained 2 to 78 scats per latrine (x-bar=9.2; S.D. = 13.8). The most common sites for latrines included elevated leaf or moss covered banks (51.2%), beaver lodges or bank dens (17.1 %), and beaver scent mounds (12.2%). Other latrine sites included felled logs over open water, bare soil along elevated banks, and exposed sandbars. Otter presence …

Avoidance Learning And Memory In Largemouth Bass (Micropterus Salmoides) Fed Bufo Tadpoles, Randy John Gawlik

Masters Theses

Tadpoles of the American toad (Bufo americanus) have been shown to be distasteful to largemouth bass (Micropterus salmoides) predators who learn, on the short term, to avoid them. How long bass retain this learned avoidance of Bufo larvae is unknown so an experimental design was constructed in an attempt to answer this question.

Largemouth bass were divided into four treatment groups. Two groups were initially fed exclusively larvae of Bufo americanus (one group was fed large tadpoles, the other group fed small larvae). Similarily, the other two groups were initially fed spring peeper (Hyla crucifer …

Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel

Masters Theses

Twelve Genera (spanning three Families) of Malaysian Turtles were studied to determine whether bone lengths could be correlated to mode of locomotion. Ulna, humerus, tibia, femur, coracoid (among others) were measured and results were presented graphically. Five of the genera were observed singly in a large aquarium. Data were recorded on the amount of time each spent in different locomotor modes. Both limb length data and aquarium observations suggest that turtles can be grouped into three main locomotor habits (i.e. terrestrial walking, bottomwalking, and swimming). The terrestrial group includes the genera, Geochelone, Kinixys, and Gopherus. Bottomwalkers include …

Survival Strategies Of Invertebrates In Disturbed Aquatic Habitats, Rosemary J. Mackay

Journal of the Minnesota Academy of Science

Disturbance in aquatic habitats may be caused by drought, flood , changes in temperature, and unusual or unnatural introductions of particulate or dissolved substances from the surrounding land. Aquatic invertebrates survive disturbance by moving to a refuge or alternative habitat or by having resistant or specially protected stages in the life cycle. Some invertebrates are able to exploit the richer and more available food materials that may result from the disturbance. Most species in disturbed aquatic habitats are efficient colonizers; they combine one or more survival strategies with high powers of dispersal, rapid growth rates, and characteristics of ecological generalists.

The Response Of Invertebrates In Temporary Vernal Wetlands To Altosid Sr-10 As Used In Mosquito Abatement Programs, Ronald W. Lawrenz

Journal of the Minnesota Academy of Science

Three temporary vernal wetlands on the Bayport Wildlife Management Area in eastern Washington County, Minnesota, were divided by sandbag barrier into treatment and control areas. Designated areas were treated with Altosid® SR-10 briquets at standard mosquito control rates. Invertebrate populations were monitored weekly using net sweeps, column samples, and ocular estimates.

The development of Eubranchtpus bundyi, Lyncerus sp, and Daphnia sp., the three major components of the invertebrate fauna, was delayed by as much as one week in site 47. Similar developmental lags were noted for E. bundyi populations in the treated portions of sites 6 and 32. Delay of …

Mosquito Control And Minnesota Amphibians, Tom R. Johnson

Journal of the Minnesota Academy of Science

Minnesota has 19 species of amphibians. Most of these animals have habitat requirements that include natural marshes, woodland ponds, and temporary pools. Amphibians need a stable and unpolluted environment. Changes in the pH of marshes or other aquatic habitats can be detrimental to Minnesota's amphibians. Habitat loss through the draining of marshes will be especially damaging. Several questions concerning mosquito control and its effects on amphibians need to be addressed.

Postnatal Osteology Of The Northern Grasshopper Mouse, Onychomys Leucogaster, Joe W. Bailey, Gary A. Heidt

Journal of the Arkansas Academy of Science

Two hundred forty-two specimens of Onychomys leucogaster, ranging in age from day of birth to the twenty-eighth day were cleared and stained using both Alizarin KOH and Alcian Blue/Alizarin-Trypsin staining methods. Thirty centers of ossification were studied. The data demonstrate the following: 1) skeletal centers of the appendicular skeleton ossify and mature earliest; 2) a new sesamoid bone lateral to the distal condyles of the femur was discovered; 3) the skeletal ossification of the baculum is present at one day of age; 4) a high degree of individual variation precludes aging of this species by skeletal maturation.

Effect Of Edwardsiella Ictaluri Infection On Plasma Corticosterone Levels In Channel Catfish (Ictalurus Punctatus), Janice L. Cooper, Stanley N. David, John K. Beadles

Journal of the Arkansas Academy of Science

Channel catfish (Ictalurus punctatus) were innoculated with a new host specific bacterium, Edwardsiella ictaluri, to observe the influence of bacterial infection on plasma corticosterone levels at various temperatures. The fish were innoculated intraperitoneally. The infected fish were separated from the controls. Plasma corticosterone concentrations were determined by radioimmunoassay. The plasma corticosterone concentrations in non-innoculated catfish were about 6.15 ng/ml and nearly 5.63 ng/ml in the infected fish. The lower level of the hormone in the infected catfish was not significantly different from the control level. High temperature was a stress factor which increased plasma corticosterone levels whereas E. ictaluri retarded …
